1989 Map of Termo

About this map

Termo sits at the western edge of the expansive Madeline Plains, a high-altitude basin where the Southern Pacific railroad line meets the highway. This late 1980s survey captures a sparse ranching and transportation landscape defined by the transition from the level floor of the plains to the broken terrain of Schott Canyon and the prominent Buttes to the northwest. The presence of the Cem near the northern boundary and localized water sources like Ducasse Reservoir and Tunnel Spring indicate the essential infrastructure required for settlement in this arid corner of Lassen County. The map also documents industrial activity through the Borrow Pit, while natural features like Fleming Spring mark the few reliable water points in the southern reaches of the quadrangle.
